Problems solved by technology

[0002] For the current general-purpose ice machines, especially edible ice machines, there is no edible ice machine that can achieve large-scale production. At present, the largest daily production capacity is less than 1500 kg, which is mainly limited by the refrigeration technology. The main reason is It is impossible to realize automatic deicing
If recycling can be achieved, only 1 ton of circulating cooling water is needed to meet the technological requirements of the refrigeration system for the daily production of 810 kg of ice cubes, and the cooling water consumption rate is less than 3%.
[0004] From the above, when deicing is performed, the refrigerant only flows through the ice maker and compressor through the heat supply valve 14. Practice has proved that as the deicing continues, this cycle causes the temperature of the refrigerant to enter the compressor to increase after being compressed. The lower and lower, when it lasts for a certain period of time, the temperature of the refrigerant gas discharged from the compressor is very low, and even cannot reach the temperature required for deicing, which will easily cause insufficient heating, affect deicing, and make the deicing time very long. It takes 2 minutes to 3.5 minutes, which directly leads to increased power consumption
De-icing cannot be achieved if the ice maker is large, or if the ice cubes are thick
[0005] At the same time, this system can only meet the deicing requirements of two 450kg / 24-hour ice makers. If the number of ice makers increases or the specifications increase, normal deicing will not be achieved.
Therefore, this system limits the development of the ice machine to the direction of large-scale energy saving and water saving
[0006] In addition, the system has an obvious design error that does not meet the refrigeration technical specifications, that is, the high-temperature and high-pressure gas discharged from the compressor enters the ice maker through the heating valve to exchange heat with ice cubes, and becomes a gas-liquid mixture and enters the compressor.
When the liquid gradually accumulates inside the compressor, it is easy to cause liquid shock of the compressor, which is absolutely not allowed in refrigeration technical specifications, which will cause damage to the compressor

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an ice-making system that utilizes the exhaust heat of a compressor of the system itself for deicing. Background technique [0002] For the current general-purpose ice machines, especially edible ice machines, there is no edible ice machine that can achieve large-scale production. At present, the largest daily production capacity is less than 1500 kg, which is mainly limited by the refrigeration technology. The main reason is The problem is that automatic de-icing cannot be achieved. In addition, small ice machines have high energy consumption, and the cooling water often cannot be recycled, resulting in a serious waste of cooling water resources. Taking an edible ice machine with a daily output of 810 kg as an example, as much as 10 tons of water is used for cooling a day, and the water is often only used for one cooling and is directly discharged as waste water, and the ...
